Spill-related symptoms • More than 300 people had come forward with Spill-related symptoms • Chest pain • Coughing • dizziness • Headaches • Respiratorydistress • Vomiting • It is difficult to clinically distinguish toxic symptoms from other common illness.
Damage caused by VOCs • Respiratory problems • Temporary central nervous system troubles • Cancers • Dermatitis & skin infection
Supporting literature • Scientist combed the literature for clues about long- and short-term impacts • 270 people who work on clean-up of the Exxon Valdez spill filed claims for respiratory problems. • Those who worked most closely with the spilled oil had “a greater prevalence of symptoms of chronic airway disease," ”
Spill-related health damages • Workers & volunteers • Exposed to the most VOCs evaporating from the light oil floating on the ocean surface • Exposed to compounds from chemical dispersants being used • Contact with weathered oil, which clumps up and can coat beaches and animals
Spill-related health damages • Residents in the affected communities are also at risk of • exposure to wither crude oil in the water or weathered oil on the beach • Inhalational exposure to chemical compounds • Eating potential contaminated sea food
Spill-related psychological ailments • The psychological ailments prompted after dealing with spilling • Higher rate of depression • Anxiety • Posttraumatic stress disorders
Conclusion • “The impact of frequent natural and human-caused disasters such as Hurricane Katrina and now the oil spill, further strains populations that are already experiencing a great deal of stress." • “Psychological and social impacts may be as significant as the physical impacts of the Gulf oil spill.”
Discussion-1 • Why do people suffer from psychological ailments after the oil-spilling disaster? • What is the deeper meaning?
Discussion-2 • How can we approach to the balance between Nature & Culture?
Discussion-3 • How will our future world become?
